Specification of Letters Patent.

Patented Dec. 12, 19118.

Original application filed January 28, 1914, Serial No. 814,959. Divided and this application filed July 17, 1914. Serial No. 851,621.

To all whom it may concern:

Be it known that I, JOHN E. ALLSTEADT, citizen of the United States, residing at Hastings, in the county of Adams and State of Nebraska, have invented certain new and useful Improvements in Door Structures for Metallic Storage-Bins, of which the following is a specification.

My invention relates to metallic struc: tures, and particularly to metallic storage bins, such as are illustrated and described in my pending application Serial No. 814,959, filed Jan. 28, 1914, of which application this is a division.

An object of my present invention is to provide means whereby grain or other material may be readily discharged into a storage bin or readily removed therefrom.

A still further object is to provide a bin with an upper receiving door, a lower doorclosed opening from which the grain may be shoveled, and an intermediate opening likewise closed by a door and provided with a grain spout so that the greater portion of the grain contained within the bin may be readily discharged into wagons.

Still another object is to so construct a bin that access may be had to the grain in the bottom of the bin and to permit the grain to be shoveled from the bottom of the bin without danger to the operator.

A. further object of the invention is to improve the detailed construction of bins and particularly the structure of the doors, chutes, and allied parts, whereby grain may be discharged from the bin and to prevent the entrance of small animals or insects into the bin through the joints of the door closures.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein 2-:-

Figure l is a longitudinal vertical section of a bin constructed in accordance with my invention. Fig. 2 is a fragmentary perspective view of a portion of the side wall of the bin showing the lower loading door and the unloading door with its spout. Fig. 8 is a fragmentary transverse section on the line 3-3 of Fig. 1. Fig. 4 is a like view on the line 44 of Fig. 1. Fig. 5 is a like section on the line 5-5 of Fig. 1.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawing by the same reference characters.

The bin illustrated in the drawings is preferably circular in form and the struc ture of this bin is clearly described and illustrated in my pending application above referred to. Preferably, the sides of the bin are formed of sheets of metal connected to each other by bolts and the bin is provided with a floor and with a roof, the floor being designated generally 7 and the roof 11, the side wall of the bin being designated 2. The detailed construction of the side wall, floor and roof of the bin forms no part of my present invention and, therefore, requires no extended description. Preferably, a ventilating flue passes up through the center of the bin whereby moisture in the grain may be dissipated.

The wall of the bin is provided with a loading door opening 53, as shown in Fig. 2, which is disposed adjacent the roof of the bin. The margin of this door opening is strengthened by angle irons 54 having outwardly extending flanges forming the door frame. The outwardly extending flanges of the upper and lower angle irons 54 are laterally extended at one side to form a support for the pivots upon which the door 55 is hung. This. door 55 may be made of sheet metal provided at its margins with inwardly turned flanges 56 which are so disposed that when the door is closed the flanges will fit over and have snug engagement with the outwardly projecting flanges of the angle irons 54 and 54 The upper and lower flanges 56 are extended beyond the inside margin of the door for engagement with the ears formed by the extensions of the flanges 54 and are pivoted to these extensions by means of bolts 57 or other suitable pintles. The door is provided with any suitable hasp 58 engaging with the keeper 59 on the body of the bin and permitting the door to be locked'when closed. Interiorly of the door opening 53 there is attached to the wall of the bin the plate 60 having inwardly inclined sides riveted to the wall of the bin, this plate being provided with the central opening 60 closed by a sliding door 60", and having an integral grain cap 61, as shown in Fig. 1.

Below the opening 53 the side wall of the bin is formed with a discharge opening closed by a door 62. The door opening is relatively long and as illustrated, extends across the two tiers 2 and 2, the lower portion of the door opening being disposed only about two inches above the floor section 7. This door opening is framed on the exterior by angle irons 63 and 6 lwhich are riveted to the sheet metal forming the wall of the'bin, these angle irons having outwardly projecting flanges. The angle irons 64: are extended laterally at one end to form ears 65. The door 62 is also framed by outwardly projecting flanges 66 and 67 so disposed that when the door is closed the flanges will have snug engagement with the outwardly projecting of the door opening.

flanges of the angle irons 63 and 64: and the flanges 66 are extended laterally to form ears 68 through which pintle bolts 69 pass.

The door is provided with a hasp 70 adapt edto engage with the keeper 71 whereby the door may be locked to its closed position. Above the door frame is a weather cap 72 which projects out far enough to extend entirely beyond the upper flange 64 and beyond the door when the door is closed, thus preventing rain from dripping down upon the door and possibly entering the bin in this manner.

In order to provide for the removal of grain from the bin by means of a spout so that when suflicient grain is in the bin the grain may be conducted to a wagon and allowed to run by gravity thereinto, 1 mount upon the inside face of the bin the casing 73, as illustrated in Fig. 4. This casing consists of a sheet of metal 7% extending approximately parallel to the wall of the bin, the side margins of the sheet being inwardly bent as at'75 and then laterally bent as at 76 and riveted to the wall 2 by rivets 77. The sheet metal 7 4 forming the back of the casing 73 is formed with a central opening 78 and on each side of this opening there are provided guides 81 between which slides a door 82 having a handle 83 whereby it maybe readily. raised and lowered. This door 82 constitutes a cut-off which permits the opening 78. The lower edge of this cutoff when the cut-off is closed, abuts against a strip 85 (see Fig. 1) which extends across the outer face of. the plate 74 at the bottom The upper portion of the strip 85=is outwardly flared and forms a seat to receive the lower edge of the door .82.. The upper'outer edge of the strip 85 extends a; considerable distance above the lower line ofthe door 82 when the latter is closed, as shown in'Fig. 1, and thus also serves as a retarder to the gram. 60

A chute or spout 86 is pivotedto brackets 90 extendingfrom the wall 7 l of the bin, and bears at its inner end against the member 85 and beneaththeoutwardly projecting upper portion of the same when the chute is in open position. This chute or .spout is also made of sheet metal and has upwardly extending sides 87 formed at their upper ends with lat erally deflected cars 88, these ears being within this space, as illustrated in Fig 1.

When, however, the spout is turned down as shown in Fig. 2, it will project beyond the outer walls of the bin in position to dis charge grain either directly into a wagon or into a chute leading to a wagon or other receptacle. The upper end of the casing 7 3 is closed by a grain cap 7 9, as seen in Fig. 1, the outer edge of this cap being convexly rounded to conform to and rest against the inner face of the bin wall. preferably formed integral with the plate 74:. By this arrangement when the chute 86 is in its lower or operative position, the outwardly projecting upper portion of the The i I The grain cap is member 86 in coaction with the door 82 rc- 3 tards the flow of the grain, and this flow can be controlled by adjusting the door, as will be obvious.

Immediately beneath the lower edge of the plate 7 4 there is disposed a downwardly and inwardly extending plate 91 which forms the top of a passage 92. This plate 91 is downwardly bent at the sides as at 93 and rests upon the bottom or floor 7 of the bin.

The downwardly and inwardly inclined top 91 of this passage 92 will cause any grain which may be resting upon this top to slide oil into the bottom of the bin, when the level of the grain in the bin is reduced below the level of this wall 91. At the same time the passage 92 permits the grain in the lower portion of the bin to be shoveled out and discharged through this passage 92 after the level of the grain has fallen below the level of the discharge opening which is closed by the slide 82. hile ordinarily, when the bin is full, grain will be discharged through the opening closed by the slide 82 or cut-oil, yet it is always possible to enter the passage 92 and shovel the grain out from the bottom of the bin, as the roof of this passage will support any grain and prevent the filling up of this passage with grain. The strip 85 is for the purpose of preventing grain from leaking through the oint between the upper 94, as illustrated in Fig. 1, which strip extends over the joint between the bottom or floor of the bin and the side wall thereof. The bin may, of course, be supported on any suitable foundation, and this foundation may be so constructed as to permit the ingress of air beneath the bin so that the air may pass up through the central ventilating flue. I have shown for this purpose transversely extending wooden sills 95 upon which the bin rests, these sills being in turn supported upon suitable foundation sills 96 or other suitable foundation, it being designed to lift the structure sufficiently from the ground to permit air to freely pass beneath the structure.

The angle irons 63 are perforated at intervals as at 102 to permit a brace 103 (see Fig. 1) to be transversely positioned across the opening through which the spout 86 operates and thus hold the spout in its raised position and prevent any unauthorized tamporing with the cut-0E slide 82.

As before remarked, this device is particularly intended to be shipped in sections and set up by the purchaser at any desired location. It is for this reason that the parts are made of sheet metal so as to be light, and so formed as to be conveniently connected to each other. The bin may be set up in any suitable location. and is readily transportable to some other location whenever desired. When set up it is thoroughly strong and is proof against the inroads of rats, mice and insects. The grain is ordinarily discharged either into the receiving door in the roof of the bin or into the upper door 53. The upper door 53 is found particularly convenient for spouting the grain into the bin directly from a threshing machine. As the bin is filled, boards are disposed across the openings so as to prevent pressure of the grain from forcing the doors of the bin. When the bin is filled to capacity there will be a draft of air passing up through the center of the mass of grain at all times and any moisture which may be contained within the grain will be thereby dissipated, thus preventing the grain from sweating and rotting.

When it is desired to remove the contents of the bin the grain may be discharged either through the opening controlled by the cut-off 82 or through the passage 92, as desired. T have found the cut-off and spout of great convenience in filling wagons from the bin and also for using the grain for feeding purposes, it being possible to allow a very small quantity of grain to pass out from the bin and then to close the slide again. It will be noted that when the door 62 is closed it is impossible for stock to accidentally open the door and thus get at the grain within.

Having thus described the invention what is claimed as new is:

1. A storage bin having an opening in one of its walls, a strip attached to the bin beneath said opening with the upper portion thereof flaring upwardly and outwardly and spaced at its upper edge from said opening and above the lower line of the same, a clo sure for the opening seating when closed upon the flaring portion of the strip, and a chute mounted to swing from said bin and with its inner edge extended to engage when open beneath the flaring portion of the strip, said strip coacting with the closure to retard the flow of the material and enable the discharge to be controlled.

2. A storage bin having an opening in one of its walls, a strip attached to the bin beneath the opening with its upper portion flaring upwardly and outwardly and spaced at its upper edge from said opening and above the lower line of the same, a closure for the opening seating when closed upon the flaring portion of the strip, brackets extending from the wall of said bin above the upper line of the strip and in advance of the same, and a chute having vertical sides and pivoted by said vertical sides to said brackets, the inner edge of said chute being extended to engage when open beneath the flaring portion of the strip, the strip and the closure coacting to retard the flow .of the material to control the discharge of the same from the bin.

In testimony whereof I ailix my signature in presence of two witnesses.
